Ka fkg. 1 display; about the proposed device (front part) front view; in fig. 2 is the same (right part) in FIG. 3 is a section along A-A in FIG. 2 in FIG. 4 - the separate parts of the device (the interaction of the solenoid drums, strings, spools, winding wire), plan view.

The device comprises a frame 1 on which the drives 2 are located with the pull drums 3. The closed string 4 is tensioned on the drums 3 and is passed through the windows of the cores 5 fixed in the fixture for fixing the cores b. A fixture for fixing the core is placed between pulling drums 3. One end of wire 7 is attached to the string, and the other end is fixed in a fixture for fixing cores 6.

On either side of the fixture for fixing the cores 6, there are mechanisms for issuing a margin of wire, made in the form of two spools 8 mounted on rollers 9, which sit on axes 10 fixed on the frame 1.

Between the spools 8 there is a drive ring 11 mounted on the rollers 12 and provided with an axis 13 with a folding roller 14 .. The spools 8 are kinematically connected through shafts 15 to brake motors 16, and the drive ring through shaft 17 to a drive motor 18.

The device is equipped with electrically automated units (not shown), which serves to actuate the locking electromagnetics.

19, as well as to control the electric motors 16, 18, ONLY 2 and the turn counter (not shown).

The wire margin is on the reel.

20. The described device operates as follows.

The drive 2 with pull drums 3 communicates the movement of the closed string 4, for example, clockwise, and the fixed end of the wire 7 moves through the windows of the first row of cores 5. When the knot passes, the wire ends are fixed along the working surface of the pull drum 3, the wire section comes from the string. The end of the wire forms, using the left roller 14, in its initial position, a half-closed loop in the path of the wire. Last at the same time throws in the groove roller 14.

After that, the left-hand drive of the left-hand mechanism for issuing a reserve of wire and its roller 14 is turned on, rotating together with the driving ring 11 away from the center

LechIkoe B, pulls the wire out of the loop branch fastened to the string through the windows of the first row of cores and places it in the notches of the left spool 8 until the entire measured piece of wire stock is removed from the reel 20, stops in the extreme position and keeps the wire in a tight state with the necessary effort. Without stopping, the string with the end of the wire passes through the windows of the second row of cores and along the working surfaces of the right pull drum 3, where the wire separates from the string, again forms a semi-closed loop, which is thrown into the groove of the right roller 14. After that, the drive turns on the right drive ring 11c with the roller 14, and the roller pushes the wire by the loop branch that is not attached to the string through the windows of the second row of cores and puts it into the grooves of the right spool to select the entire piece of wire. At the same time, the left roller coils the wire from the left spool and holds it in a groove with the necessary tension, which is created automatically by the brake motors 16 and the drive motor 18, which in this case operates in the brake mode.

When the left roller 14 approaches the end of the magnetic circuit, after the entire supply is pulled from the spool, the wire is automatically dropped from its groove. The wire is placed close to the end of the magnetic circuit with a force that is generated by driving the right roller 14 through the semi-closed loop of the wire located on this roller. After resetting the wire, the left roller is automatically set to its original position, where it is fixed against rotation by the locking electromagnet 19.

The right roller 14, going to the extreme position, holds the wire in a tensioned state, and the string drags through the openings of the first row of cores a second time the wire end at the same time and brings it to the half closed loop to the left stretched drum.

Claims (2)

Thus, the actions of the mechanisms described above are repeated until the measured length of the wire is fully laid. After the device stops, when the specified number of turns in the winding is reached, the wire is cut off from the string and from the reel. It is possible not to cut the wire from the coil, but to continue winding this winding without cutting the wire with the second part of the stock, but in the opposite direction compared to winding the first part of the stock. The cut ends of the wound wire are retracted to the sides and fixed in special fixture clamps. To wind the next winding, you must again secure the end of the next measured length of wire margin on the string. Thus, the size of the device is significantly reduced, and the versatility of the application for winding windings of various lengths is increased. The invention The device for winding transformers with ring-shaped cores, containing pull drums, on which is attached a closed string with an assembly for fastening the end of the wire, a mechanism for issuing a margin of wire and adjusting the fixation of the core, characterized in that overall dimensions of the device and increasing its versatility; the mechanism for issuing a margin of wire is made in the form of two spools, the roll of which contains two rings with grooves on the outer surface mounted on both sides and for fixing the cores with the possibility of free rotation around its axis, and folding rollers associated with their drive and located between the rings of the spools With the possibility of rotation around their axis.
